Recovery of Fingerprints using Photometric Stereo
نویسنده
چکیده
We demonstrate the use of photometric stereo to enhance the recovery of both visible and plastic fingerprints. Examples are given that show the recovery of visible prints from rough surfaces and a plastic print from a patterned surface. This approach improves the quality of the print by reducing the effects of variations in the background surface. It provides a cheap and effective way to improve the quality of the image before enhancement and recognition algorithms are applied.

3D Reconstruction Using Shape from Photometric Stereo and Contours
In this work, we further discuss an approach to 3D shape recovery by combining photometric stereo and shape from contours methods. Surfaces recovered by photometric stereo are aligned, adjusted and merged according to a preliminary 3D model obtained by shape from contours. Comparisons are conducted to evaluate the performances of different methods. It has been found that the proposed combinatio...
متن کاملA Streamlined Photometric Stereo Framework for Cultural Heritage
In this paper, we propose a streamlined framework of robust 3D acquisition for cultural heritage using both photometric stereo and photogrammetric information. An uncalibrated photometric stereo setup is augmented by a synchronized secondary witness camera co-located with a point light source. By recovering the witness camera’s position for each exposure with photogrammetry techniques, we estim...
متن کاملAlbedo Recovery Using a Photometric Stereo Approach
This paper describes a method for the estimation of surface reflectance values using a photometric stereo approach. Evaluations show that surfaces rendered with reflectance values calculated by the proposed method have more realistic appearances than those with constant albedo.
متن کاملShading Based 3D Shape Recovery in the Presence of Shadows
Shadows usually cause various problems in three-dimensional shape recovery and measurement methods. In particular shading based approaches such as shape-from-shading or the photometric stereo method produce no or wrong results if the shadows are not treated appropriately. We show how information extracted from shadows can be employed to reduce the problems caused by them. This is done for multi...
متن کاملThe 4-Source Photometric Stereo Technique for Three-Dimensional Surfaces in the Presence of Highlights and Shadows
We present an algorithm for separating the local gradient information and Lambertian color by using 4-source color photometric stereo in the presence of highlights and shadows. We assume that the surface reflectance can be approximated by the sum of a Lambertian and a specular component. The conventional photometric method is generalized for color images. Shadows and highlights in the input ima...
